Abstract: We consider the piecewise proportional hazards (PWPH) model with interval censored (IC) relapse times under the distribution-free set-up. The partial likelihood approach is not applicable for IC data, and the generalized likelihood approach is studied by Wong et al. [1]. It turns out that under the PWPH model with IC data, the semi-parametric MLE(SMLE) of the covariate effect under the standard generalized likelihood may not be unique and may not be consistent.
